Unable to install a .sh file

I am trying to use a package called mgl-tools and when I run ./install.sh, it isn't working. It used to work a few days ago.

The error:

./install.sh 
Installing MGLTools to /home/aka/Desktop/Expt 10/mgltools_x86_64Linux2_1.5.7
Installing Python Interpreter to 
tar (child): /home/aka/Desktop/Expt: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
Error in Python installation

The contents of the .sh file:

#!/bin/sh

# MGL Tools installation script
pythonargs=" "
pyoptimize=0
TarDir=`pwd`
export MGL_ROOT=""

# Parse the command-line arguments
opts=`getopt "hlc:d:" "$@"`
if [ "$?" != 0 ]
then
   echo "Usage: source install.sh [-d InstDir] [-c optimization]"
   exit
fi
set -- $opts
while :
do
    case "$1" in 

    -c) shift; pythonargs="$pythonargs -c"; pyoptimize="$1";;
    -d) shift; export MGL_ROOT="$1";;
    -l) pythonargs="$pythonargs -l";;
     
    -h) echo "Optional parameters:"
    echo "[-h]  help message;"
    echo "[ -d  InstDir] specifies installation directory (default-current directory)"
    echo "[ -c optimization] compile Python code with or without optimization:"
    echo "    0 - no optimization (generates .pyc files)"
    echo "    1 - with optimization (generates .pyo files);"
    exit ;;
    --) break;;
    esac
    shift
done

if [ "$MGL_ROOT" != "" ]; then
    # check if the user has write access to the installation directory
    if [ -e "$MGL_ROOT" ]; then
    if [ -d "$MGL_ROOT" ]; then
        if [ ! -w  "$MGL_ROOT" ]; then 
        echo "Can not complete installation - specified directory $MGL_ROOT does not have write access."
        exit 1

        fi
    else 
        echo "$MGL_ROOT" is not a directory
        exit 1
    fi
    else 
    echo Creating directory "$MGL_ROOT"
    mkdir "$MGL_ROOT"
    fi

else
    export MGL_ROOT="$(pwd)"
fi

echo "Installing MGLTools to $MGL_ROOT"

cd "$MGL_ROOT"
echo "Installing Python Interpreter to $MLG_ROOT"
tar xzvf $TarDir/Python*.tar.gz

if [ "$?" != 0 ]; then
    echo "Error in Python installation"
    exit 1
fi
echo Python installed, please wait for the rest of MGLTools to be installed 

cd $TarDir

## plaform we run on

export MGL_ARCHOSV=`$TarDir/Tools/archosv`

## add the path to the directory holding the python interpreter to your path

export PATH="$MGL_ROOT/bin:"$PATH

## use Python interpreter locally installed

PYTHON="$MGL_ROOT/bin/python"
export PYTHONHOME="$MGL_ROOT"
if [ "`uname -s`" = "Linux" ] ; then
    export LD_LIBRARY_PATH="$MGL_ROOT/lib"
fi

## run python script - install.py - to install MGL packages and create pmv , adt, and vision scripts

if [ "$pyoptimize" -eq 1 ]; then
    echo "Running $PYTHON -O Tools/install.py $pythonargs"
    $PYTHON -O Tools/install.py $pythonargs
else
    echo "Running $PYTHON Tools/install.py $pythonargs"
    $PYTHON Tools/install.py  $pythonargs
fi

unset PYTHONHOME

Solution 1:

Shell scripts do not like spaces in names. Please try renaming your directory EXPT 10 to a name without spaces; for example, EXPT10 and then try again.

EDIT: As @cocomac correctly points out, properly written scripts can and should account for spaces in names. If yours does not, renaming the file is the expedient solution. Rewriting the script and filing an issue with the publisher is another solution.
